"The United States has the most members of the top 1% global wealth group, and currently accounts for 41% of the world's millionaires," the report notes. "Our research indicates that the United States added 878,000 new millionaires [since 2017] — representing around 40% of the global increase."

A different, perhaps fairer, way to rank the richest countries in the world is to take a look at the countries where the greatest number of people are rich.

Credit Suisse ran those numbers, too, in order to compare how much wealth the median, middle-of-the-pack person has in every country.

In that ranking, Australians are the richest. And the US doesn't even make the top 10.

The US has a median wealth of $61,667 per adult, which puts the country at number 18, well behind others, including Ireland ($72,473), Taiwan ($78,177), and Korea ($65,463). Canada, on the other hand, comes in at number six, with an average wealth of $106,342 per adult.

To adjust for that, economist Darrick Hamilton, a professor at The New School, recently proposed a kind of baby trust fund system. His idea is to give all kids in the US a chunk of cash when they're born, ranging between $500 and $60,000 based on their family's wealth. That would help give all American kids a fair shot at a prosperous future, he said.

"Wealth is the paramount indicator of economic security and well-being," Hamilton told a crowd at the TED Conferences headquarters in New York in September. "It is time to get beyond the false narrative that attributes inequalities to individual personal deficits while largely ignoring the advantages of wealth."
